The forces that act on the car in motion are shown in the figure. The force F has one component in the direction of the x-axis (Fx) and another in the direction of the y-axis (Fy). We must calculate the work (W) performed by the forces acting in the direction of the movement.
Fx = F x Cos (25°)
Fx = 35 N x Cos (25°)
Fx = 31.72 N
We must use the following formula:
W = Fxd
F = 35 N
d = 50 m
W = 31.72 N x 50 m
W = 1586.04 Nxm
W = 1586.04 J
The work done by shwan on the cart as he moves along at 50.0 m length of aisle is 1586.04 J.
